IV Catheter Securement Device with Articulated Cushion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical securement devices for IV catheters are often complex, bulky, or not compatible with various medical implements, leading to inadequate securement and micro-pistoning issues.
Innovation Solution
A device comprising a base with an insertion site viewing window connected to a luer interconnection cushion at an articulation point, separated by a gap, and a cover with a luer interconnection window, both featuring adhesive surfaces for securement, made of adhesive foam padding and polyurethane film, allowing for flexible attachment and minimal movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing medical securement devices are used to secure IV catheters, then securement function is provided, but the devices become overly complex and bulky
Solution Approach 1:
The securement device is divided into three main segments: a base portion with adhesive foam for skin attachment, a cushion portion that interfaces with the Luer lock, and a cover portion that secures the catheter hub. These segments are connected by articulation points that allow independent movement, simplifying each component's function while maintaining overall securement effectiveness.
Solution Approach 2:
The device is designed to universally secure various types of IV catheters (both central and peripheral) by accommodating different Luer lock configurations. The cushion portion with its compliant material and the articulation points allow the device to adapt to different catheter sizes and insertion sites, eliminating the need for multiple specialized securement devices.
2Reliability
If existing medical securement devices are used, then securement is provided, but the devices are bulky
Solution Approach 1:
The cover portion is designed to fold over and nest within the base and cushion portions when not in use. The articulation points enable the cover to collapse into a compact configuration, reducing the device's volume for storage and transport while maintaining full functionality when deployed.
Solution Approach 2:
The device utilizes thin foam materials for the base, cushion, and cover portions. These flexible foam structures provide the necessary compliance and securement force while occupying minimal space. The thin film nature of these components allows them to conform to the catheter and skin without adding significant bulk.
3Reliability
If existing securement devices are used, then catheter attachment is achieved, but compatibility with various medical implements is limited
Solution Approach 1:
The cushion portion is designed with a universal interface that accommodates standard Luer lock connections used across different IV catheter types. The compliant foam material adapts to various catheter hub sizes and shapes, allowing the same device to securely attach both central and peripheral IV catheters without modification.
Solution Approach 2:
The articulation points between the base, cushion, and cover portions allow the device to dynamically adjust its configuration to match different catheter positions and angles. This dynamic adaptability ensures securement effectiveness across various medical implement configurations and patient anatomies.
4Reliability
If existing securement devices are used, then catheter securing is provided, but movement and micro-pistoning occur when in situ
Solution Approach 1:
The articulation points between components allow the device to dynamically absorb movement forces without transmitting them to the catheter insertion site. When movement occurs, the articulation points flex and adjust, maintaining stable catheter positioning while accommodating skin or catheter movement elsewhere in the device structure.
Solution Approach 2:
The compliant foam materials in the base, cushion, and cover portions act as flexible elements that absorb micro-pistoning movements. These foam structures deform elastically to accommodate small movements and then return to their original shape, preventing the transmission of movement to the catheter hub and maintaining stable securement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a simpler, more versatile securement method that minimizes movement and pressure on the skin, ensuring better securement of IV catheters with reduced risk of trauma, while being compatible with both central and peripheral IV catheters.
Implementation Method 1
The device preferably comprises a base with an insertion site viewing window connected to a luer interconnection cushion at an articulation point and separated from the cushion by a gap. The bottom surface has an adhesive.
